About this source
The Open Parser for Systematic IUPAC Nomenclature from the University of Cambridge. It interprets the name itself, so it works for new compounds from your own synthesis that PubChem has never seen, and returns SMILES, InChI and InChIKey.
Questions you can ask OPSIN
Type them into Kahubi’s chat once the source is connected.
“Look up a compound by name or CAS number and list its structure, properties and hazard statements.”
What comes back: The database record with identifiers (InChIKey, CID) and a link to verify it at the source.
What the assistant can do with it
The 1 tool this server offers to Kahubi. The assistant picks the right one for each question.
opsin_name_to_structureConvert a systematic (IUPAC) chemical name into a structure by rule, not by lookup: works for compounds no database lists.
Good to know
- Hosted by Kahubi. Kahubi runs this server itself so it stays reliable enough for research use.
- Cited, checkable answers. Results are treated as retrieved material and cited with the source’s own identifiers, so you can open every record the answer relied on.
- Your files stay private. Only the search the assistant writes for your question is sent to OPSIN.
